Process and Application Parameters [300]
Section 11-3
Deceleration Time Motor Potentiometer [334]
If the MotPot function is selected, this is the deceleration time for the MotPot
down command. The deceleration time is defined as the time it takes for the
motor potentiometer value to decrease from nominal speed to 0 rpm.

Acceleration Time to Minimum Speed [335]
If minimum speed, [341]>0 rpm, is used in an application, the VSD uses sep-
arate ramp times below this level. With Acc>MinSpeed [335] and Dec<Min-
Speed [336] you can set the required ramp times. Short times can be used to
prevent damage and excessive pump wear due too little lubrication at lower
speeds. Longer times can be used to fill up a system smoothly and prevent
water hammer due to rapidly exhausting air from the pipe system.
If a Minimum speed is programmed, this parameter will be used to select the
acceleration time parameter [335] for speeds up to minimum speed at a run
command. The ramp time is defined as the time it takes for the motor to accel-
erate from 0 rpm to nominal motor speed.
